Of incidents, curious, comic, and tragic, connected with the locality the catalogue is long, but we must make our recital of them brief. We have before referred to Professor Kalm's notice of the fall of a portion of Table Rock previous to 1750. Authentic accounts of like events are the following: In 1818 a mass one hundred and sixty feet long by thirty wide; in 1828 and '29 two smaller masses; also in 1828 there went down in the center of the Horseshoe a huge mass, of which the top area was estimated at half an acre. If this estimate was correct, it would show an abrasion equivalent to nearly one foot from the whole surface of the Canadian Fall. In April, 1843, a mass of rock and earth about thirty-five feet long and six feet wide fell from the middle of Goat Island. In 1847, just north of the Biddle Stairs, there was a slide of bowlders, earth, and gravel, with a small portion of the bed-rock, the whole mass being about forty feet long and ten feet wide. About every third return of spring has increased the abrasion at these two points. At the first-named point more than twenty feet in width has disappeared, with the whole of the road crossing the island. From the latter point, near the Biddle Stairs, which was a favorite one for viewing the Horseshoe Fall, the seats provided for visitors and the trees which shaded them have fallen. [Illustration: FALL OF TABLE ROCK] On the 25th of June, 1850, occurred the great downfall which reduced Table Rock to a narrow bench along the bank. The portion which fell was one immense solid rock two hundred feet long, sixty feet wide, and one hundred feet deep where it separated from the bank. The noise of the crash was heard like muffled thunder for miles around. Fortunately it fell at noonday, when but few people were out, and no lives were lost. The driver of an omnibus, who had taken off his horses for their midday feed, and was washing his vehicle, felt the preliminary cracking and escaped, the vehicle itself being plunged into the gulf below. In 1850, a canal-boat that became detached from a raft, went down the Canadian Rapids, turned broadside across the river before reaching the Falls, struck amidships against a rock projecting up from the bottom and lodged. It remained there more than a year, and when it went down took with it a piece of the rock apparently about ten feet wide and forty feet long. At the foot of Goat Island some smaller masses have fallen, and three extensive earth-slides have occurred.
